Abstract

PURPOSE:To smooth the load control on the occurrence of a master set by inserting and connecting a pseudo master set between a master set and a slave set so as to easily add a new function. CONSTITUTION:A control signal and a monitor signal are sent/received cyclically by time division multiplex transmission between a master set 2 and a pseudo master set 6 and between the pseudo master set 6 and a terminal equipment 4 respectively via a master set side communication line 3a and a terminal equipment side communication line 3b. When a new control function provided in the pseudo master set 6 is executed, an operation signal is sent from the master set 2 to the terminal equipment section of the pseudo master set 6. Thus, the communication line changeover means interrupts the master set side communication line 3a and the terminal equipment side communication line 3b and the pseudo master set 6 controls and monitors the new control function and the load 5 of the master set 2. When the new control function is not required, a stop signal is sent from the master set 2 to the terminal equipment section of the pseudo master set 6 and a communication line changeover means 6d connects the master set side communication line 3a and the terminal equipment side communication line 3b and the master set 2 again controls and monitors the load 5.

The operation of the load control device 1 will be described below.
First, at startup, since the base unit side communication line 3a and the terminal unit side communication line 3b are connected, if the base unit 2 transmits a load control signal, it is directly received by the terminal unit 4. As a result, the terminal 4 controls the load 5 connected to itself. Then, when the master device 2 transmits the load monitoring signal, the terminal device 4 which directly receives the load monitoring signal monitors the load 5 connected to itself and directly transmits the load state signal to the master device 2. In this way, the master 5 controls and monitors the load 5.

When performing a new control function of the pseudo master device 6, an operation signal is transmitted from the master device 2 to the terminal unit 6e of the pseudo master device 6. As a result, the communication line switching means 6d disconnects the master unit side communication line 3a and the terminal side communication line 3b. After that, the pseudo master unit 6 performs a new control function and the same control and monitoring of the load 5 as the master unit 2. When the new control function is not needed, the master unit 2 sends a stop signal to the terminal unit 6e of the pseudo master unit 6, and the communication line switching means 6d causes the master unit side communication line 3a and the terminal side communication line 3b. Connect. After that,
The base unit 2 again controls and monitors the load 5. With such a configuration, a new control function can be performed without replacing the base unit 2.

Further, the pseudo master unit 6 confirms the load control signal and the load monitoring signal which are cyclically transmitted and received when the master unit 2 is operating, by the master unit side communication means 6b, and the transmission and reception is performed. If stopped, timer 6f measures the stop time. If the stop time exceeds a predetermined time, it is determined that the master unit 2 has failed, and the communication line switching means 6d disconnects the master unit side communication line 3a and the terminal side communication line 3b. After that, the pseudo master
6 performs control and monitoring of load 5 instead of base unit 2 or a new control function. With such a configuration, it is possible to prevent an uncontrollable state and smoothly perform control even if the base unit 2 fails.

Since the load control device of the present invention inserts and connects a pseudo master unit having an alternative function or a new function of the master unit between the master unit and the slave unit, there is no need to replace the master unit and the load controller can be easily replaced. A new function can be added to. Further, even if the parent device fails, the pseudo parent device can perform the substitute function, and thus the load can be smoothly controlled.
